Icemelt

Transmutation This spell causes solid, non-magical ice to vaporize, dissipating into the surrounding atmosphere without fog, water runoff, or heat. You affect a 10-foot-square area to a depth of 1 to 4 feet; you can orient it vertically to ablate a wall-like structure. Natural and magical ice cannot form in the affected area for 2d4 hours thereafter. Ice within an organic mass (such as a frozen body) is unaffected by this spell.
